I would like to point out two misunderstandings in the text of Dawkins’ letter. I did not argue ‘that mammals are unique in having behavioural needs’, but that mammals are unique in having ‘psychological needs’ which are ‘needs of the mind’ and relate to the nature of mammalian brains and survival strategies. I did not suggest that birds do not have behavioural needs.
